Geotechnical Engineer Job Descriptions, Average Salary, Interview Questions

What Does a Geotechnical Engineer Do?

Geotechnical engineering is a mix of engineering and science, and they may work in construction determining whether the land is safe to build or they may work with other scientists in tracking climate change. These engineers are very important, especially when it comes to the overall success of construction projects. They ensure there is no possibility of unsafe ground being built on, preventing homes and buildings from being built upon soil that could cause a landslide, avalanche, or other damage.

A critical skill needed for this job is math because geotechnical engineers need to analyze data and be able to study the geology of a specific area. A bachelor’s degree in civil engineering or in another engineering field is required in order to be considered for this job. Most geotechnical engineers will also go beyond their degree and receive Professional Engineering licensure. They must also have expert knowledge in CAD software, as well as Microsoft Office Suite.
